STRIKE? AND JOINTER'.

Application filed May 4-, 1922.

To all whom it may concern:

Be it known that l, Josnrrr M. HULL, citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have i vented certain new and useful Improvements in Strikers and Jointers, of which the following is a specification.

This invention relates to new and useful improvements in a brick layers striker and jointer.

One object of the invention is to provide a tool especially designed for the purpose of finishing the cement joints between the brick, in the work of brick laying.

Another object oi the invention is to provide a simple tool of the character described which may be cheaply constructed and easily handled.

With the above and other objects in view the invention has particular relation to certain novel teaures of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a plan view of the device.

Figure 2 shows a side view, and

Figure 3 shows a side view of a modified form of runner employed.

In the drawings the numeral 1 designates the handle which is formed into a convenient grip. One end of this handle is formed with the neck 2 whose free end is formed into a bearing 3 designed to receive an ordinary nail which. is passed upwardly therethrough, and which is secured therein by means of a thumb screw which is threaded through the bearing 3. The other end of the handle is reduced and outwardly threaded forming a spindle 6 provided to receive the clamp nut 7. A runner 8 is provided whose ends are upwardly turned, and one of said upwardly turned ends 9 has a bearing which receives said spindle 6, said end being clamped by the clamp nut 7 between said nut and the adjacent end of the handle. The bearing 3 has the laterally extending spindles 10, 10 on which the bearing wheels 11, 11 are mounted to rotate. In the process oi laying brick it is usually desirable to re- Serial No. 558,397.

more a certain part of the cement forming the joint between the brick so as to give a better appearance to the finished structure. in order to do this the device herein described is employed and when used the bearings 11 run along the outer faces of the adjacent hriiand the head of the nail 4 scrapes out the cement between the brick while it is in a plastic state. The implement is then. reversed and the runner passes along said oint and smoothes down said cement giving a more perfect joint.

it is de ired the nail d and the runner 8 may be d ensed with and the form of runner shown in Figure 3 employed. This runner is indicated by the numeral 10 and is formed with shank 11 which may be in serted. through the bearing 3, as illustrated in dotted lines in Figure 2, and held therein by the thumb screw 5 lVhen this form oi? runner is employed the plastic cement of the joint may be scraped out and smoothed at one stroke of the implement.

What ll claim is A device of the character described includinga handle formed into a grip, a depending neck secured to one end of the handle and whose free end is formed into a bearing, a striker formed with a shank which is fitted through said bearing, a thumb screw threaded through said bearing and provided to secure said shank therein, laterally extending spindles carried by the bearing, bearing wheels mounted to rotate on said spindles the other end of said handle being reduced, a runner whose ends are upwardly turned, one of said upwardly turned ends being formed into a bearing to receive the reduced end of the handle and a clamp nut threaded onto said reduced end to secure the runner to the handle.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
